The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Semaphore, not the verdict.
| Signal | Score | Weight | Contribution | Evidence |
|---|---|---|---|---|
| Security Posture | 80 | 26.00 | 2080.0 | ✓ |
| Capabilities | 58 | 14.00 | 809.4 | ✓ |
| Pricing Transparency | 100 | 6.00 | 600.0 | ✓ |
